- Specification of Letters Patent. Application filed July 15, 1912. Serial 1%. 709,469;

-Boston, in the county of Suflolk' and' State. of Massachusetts, have invented certain newand useful Improvements-in Food Composition-for. Stock, of which'thefollowing is a specification.

[This invention relates to v food comp osiv tionsfor cattle or other live stock and to methods of- 'preparingthe same, the object of theinventionbeing the preparation of an nutritious 'food-,'

inexpensive, palatable and product from cheap materials, andespecially from materials which are commonly regard-- ed as waste products,

According to the present ligno-cellulose, asfor example corn "stalks,

'bagasse or other. residues of sugar-cane or of other sugar-producing plants, sawdust, or "the like, are digested in presence of hydrochloric acid or chlorin under conditions .to convert a substantial proportion of the charge into sugars Thereafter the free hy-.

is neutralized by means of.

drolyzin'g agent sodium carbonate or equivalent reagent,

whereby sodium chlorid is formed; or incase free chl'orln is present there 1s. some formation of sodium hypochlorite which is thereafter reduced to chlorid. The resulting product "is a I palatable and nutritious I stock. -food, which may be mixed with protein foods,

as may be preferred. Essential constituents I of the food-product are the sugars resulting from the hydrolysis, and the sodium chlorid as cotton-seed meal or other meal cake,'or with such. other nutritive substances derived from the hydrolyzing-agent' invention, 'materials consisting largely of cellulose 'or The hydrolysis may be carried out in accordance, with any known or approved proc- -ess.:

shredded-[or otherwise comminuted, com mingled with about one per cent. by weight of hydrochloric 'acid dissolved in suflioient Water to moisten the charge, and digested for ten to sixty minutes by direct contact with. steam under, pressure. The cooked mass, containingra considerable proportion of sugars, is then sprayed or otherwise mixed with a highlydilute solution-of sodium carbonateuntil the free acid is neutral- .ized. 'It is thereafter dried' to expel excess moisture, and is then ready for use, either alone orfmiXed with other nutritive bodies.

'I claimfi 1. As a new article of manufac'tu re, a, food-product derived. from cellulo's'ic' ma:

terials, said food-product containing sugars resulting from the hydrolytic action ot'a chlorincontaining hydrolyzing" agent, the unconverted residue of the hydrolysis, and sodium chloridi derived from the hydrolyzing agent, and; free from excessmoisture.

2. The method of preparing food-products from ligno-cellulose, which consists in subjecting cell-ulosic materials to a chlorin= containing hydrolyzing agent under conditions to produce sugars-,'then converting the 'hydrolyzing agent into. sodium chlorid and freeingthe mass from excess moisture,

In testimony whereof I afiix my signature in presence of. two witnesses,

ARTHUR n. LITTLE.
